Dendrochilum (commonly abbreviated Ddc. in horticulture) is a genus of epiphytic, lithophytic and a few terrestrial flowering plants in the orchid family (Orchidaceae). The name of this genus is derived from Ancient Greek words dendron ("tree"), and either cheilos ("lip") or chilos ("green food"), alluding to either the flowers' large lip or to their epiphytic growth. These orchids are popular among fans of non-traditional orchid curiosities.
